1.

  Start a new application.

 

2.

  Add a Button. Edit its OnClick event:

 

#include <shlobj.hpp>

void __fastcall TForm1::Button1Click(TObject *Sender)

{

    LPMALLOC pMalloc;

    if(SHGetMalloc(&pMalloc) == NOERROR)

    {

        BROWSEINFO bi;

        char pszBuffer[MAX_PATH];

        LPITEMIDLIST pidl;

        bi.hwndOwner = Handle;

        bi.pidlRoot = NULL;

        bi.pszDisplayName = pszBuffer;

        bi.lpszTitle = "Please select a directory:";

        bi.ulFlags = BIF_RETURNFSANCESTORS |

            BIF_RETURNONLYFSDIRS;

        bi.lpfn = NULL;

        bi.lParam = 0;

        if((pidl = SHBrowseForFolder(&bi)) != NULL)

        {

            if(SHGetPathFromIDList(pidl, pszBuffer))

            {

                Caption = pszBuffer;

            }

            pMalloc->Free(pidl);

        }

        pMalloc->Release();

    }

}

 

When the user selects a directory, its path will be displayed in the caption bar.
